Hadar Tamir, Spierer's roommate at Smallwood Plaza apartments, on Monday filled in more details of that morning, saying Spierer was hanging out with her until 12:30 a.m., then went with another Smallwood resident, David Rohn, to friend Jay Rosenbaum's apartment up the street.
Spierer, Rohn and Rosenbaum watched a basketball game at Rosenbaum's, said Tamir, who is friends with Rohn and Rosenbaum. They were joined there by Corey Rossman, who lives two doors down, she said. Tamir said Mike Beth, Rossman's roommate, was also there.
A while later, Rossman and Spierer went to a bar, Tamir said, and Rohn returned to Smallwood.
About 2:30 a.m., Spierer -- who left her cell phone and shoes at the bar -- and Rossman returned to her building, where other students confronted him.
One punched him in the face, causing him to lose memory of the exchange and his interactions with Spierer after that, Rossman's lawyer said.
They then went to Rossman's building, where Beth, his roommate, put him to bed, said Beth's lawyer, Ronald Chapman.
Beth watched Spierer leave. She then went to Rosenbaum's apartment.
Tamir, who has spoken with Rosenbaum since then, said Monday that he had tried to prevent her from leaving.
"He told me he tried to make her stay and sleep on his couch but she refused, so finally after trying to convince her, she left," Tamir told The Journal News.
"He told me he watched her leave and told her, 'If you stumble then I'm going to make you come back in here.' But he watched her leave and she seemed fine so he just let her go," Tamir said.
Before leaving, Tamir said, Spierer used Rosenbaum's phone to call Rohn to see if he knew where her phone was.
Chapman, who represented Rohn in a prior public intoxication case and spoke with him in recent days about his interactions with Spierer, would only say that that "somebody" called Rohn at 4:15 a.m. and that "he didn't answer his phone because he was in bed."
He did say that police questioned Rohn.
"It's pretty clear that the police looked at his phone," Chapman said. "They wanted to talk to him and everything seemed copacetic."
